I'm going to be interested to see how the electoral map changes going forward- throughout the 2000s a lot of people are going to be migrating out of the South, and states at lower latitudes are going to end up losing influence in the electoral college as a result. The electoral vote layout for the 2012, 2016, and 2020 elections could be very regionally lopsided.
Since censuses happen once a decade, there isn't too much change, as most of the internal migration mostly occurs after 2014. The 2020 Census definitely showed massive population disparities, which will be reflected in the 118th Congress and the 2024 election. There is also talk of making censuses every five years since the internal population distribution can change very rapidly.
So seeing some butterflies like Russia returning to a Soviet state in the 1990s, have some events like 9/11 been butterflied in any way?
9/11 is not significantly changed, as much of the planning had taken place when the butterflies were let loose.
Besides ozone depletion and the direct effects of UV exposure on plant life, as well as an increasing prevalence of superstorms, how else has the environment grown worse? Are sea levels significantly higher by the present day ITTL?
Sea levels are a bit higher, but not by much. This is actually because the ozone hole over Antarctica results in more precipitation, which can offset ice loss.
Wait, “former” Peru and Bolivia? What happened there? Is there some kind of federation between the two countries, have they both collapsed, or is there something else? Apologies if someone has already asked this
Peru has collapsed. It's technically under a UN transitional government, but whatever government is left is relegated to the Amazon and is effectively a Brazilian puppet. Much of the country is governed by Shining Path wannabes, right-wing militias claiming to be the legitimate government, cartels, and indigenous statelets. Bolivia technically still exists, but again, it relies on the Argentinian and Brazilian militaries to keep order.
